Zaptiz GST
Where: Sidebar → Zaptiz GST · Needs the Accounting and AI Suite modules.
Zaptiz GST prepares and de-risks your monthly GST return:
- Computes your returns — a portal-shaped GSTR-1 and GSTR-3B built with pure arithmetic from your invoices. The AI never invents numbers.
- Catches errors early — ~20 automated checks (invalid GSTINs, missing HSN codes, place-of-supply mismatches, return reconciliation…) with a 0–100 health score.
- Answers questions — ask in plain English and get answers grounded in your computed figures.
Zaptiz GST prepares and validates; a human files on the GST portal. It is not a substitute for your CA, and it never emails customers or edits invoices — it's read-only on your data.

Running a health check
- Pick the period in the header (any of the last 12 closed months, e.g. "Jun 2026").
- Click Run health check.
- You'll get a toast like "Health check complete — score 82/100" and the tabs fill in.
The health score starts at 100 and loses 10 points per error and 3 per warning.
The five tabs
Health check
- Four cards: Health score, Output GST, Input Tax Credit (from vendor bills), Net GST payable.
- GSTR-1 breakdown — B2B (registered), B2C (small), credit/debit notes, with Taxable / CGST / SGST / IGST columns.
- GSTR-3B Table 3.1 — outward supplies, ITC (Table 4), and net payable in cash.
- HSN summary (Table 12) — taxable value and tax by HSN code and rate. Lines whose product has no HSN code appear in red as UNCLASSIFIED — set the HSN on those products (Products → edit → HSN Code) and re-run.
Findings
Every issue found, as a card with severity (Error / Warning / Info), the ₹ impact where relevant, and a concrete "Fix:" hint. Triage each one with Ack, Resolve or Ignore — your triage survives re-runs; only open findings get refreshed.
The checks cover, among others:
- GSTIN & master data — invalid GSTIN checksum, GSTIN/state mismatch, B2B customer missing a GSTIN, company GSTIN missing.
- Place of supply & tax type — missing place of supply, POS vs CGST/IGST mismatch.
- Rates & HSN — missing or malformed HSN (escalates to an error above ₹5 crore turnover), non-standard GST rates, zero rate on taxable lines.
- Return reconciliation — GSTR-1 vs 3B mismatch, ITC greater than input tax, credit note without an original invoice.
- Filing calendar — return due soon, overdue (with estimated late fee at ₹50/day plus 18% p.a. interest).
Ask AI
Type a question — "Why is my ITC higher than my output tax?" — or use the suggestion chips ("Explain my GST-3B for this period", "What should I fix before filing?"). Answers are grounded in your computed figures and metered against AI credits. The Explain return button produces a full plain-English walkthrough of the period.
Calendar
Your next filing deadlines with status badges (Upcoming / Due soon / Overdue):
| Return | Frequency | Due |
|---|---|---|
| GSTR-1 | Monthly | 11th of the next month |
| GSTR-1 (QRMP) | Quarterly | 13th after the quarter |
| GSTR-3B | Monthly | 20th of the next month |
| GSTR-3B (QRMP) | Quarterly | 22nd / 24th (by state group) |
Settings
- Filing profile: your GSTIN, home state code, filing frequency (Monthly / QRMP), and annual turnover (this drives the HSN-digit rules).
- Monthly health check: toggle Auto-run each month and Notify the accountant — the agent then computes and validates each closed month automatically and sends the accountant a summary ("GST health for Jun 2026: score 82, 2 errors to fix before the 11th").
- GSTIN validator: paste any GSTIN → Check → instant valid/invalid with the state name (it runs the real checksum).
Settings save as you edit — there's no Save button.
Tips & gotchas
- HSN codes live on products (Products → edit → HSN Code, digits only, up to 8). 4 digits are required up to ₹5 crore turnover, 6 digits above. Fill them in and re-run the health check to clear
MISSING_HSNfindings. - Intra-state sales split CGST + SGST half-and-half; inter-state sales charge IGST. Most electrical panels and components are 18%.
- You can also ask GST questions from the global AI Chat Assistant ("what's my GST this month?").
- Ask AI / Explain use AI credits and are rate-limited (about 10/minute).
